But since he's using a 1GB GPU he'll be seeing less than 2.85GB anyway at best.
Windows based x86 / 32-bit systems will only support the utilization of up to 3.5GB or so. They will never, EVER use 4.0GB. Windows just had a recent patch that allowed it to see 4+GB by reading the BIOS, does NOT mean it can use it all.
To the op: that happened to me when I needed to change RAM timings to be correct. If this happened out of the blue, you got some defective RAM. Is this a clean install or existing one that suddenly had this issue?
